Do not expose power tools to rain or wet
conditions. Water entering power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords
increase the risk of electric shock.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.

17. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
18. Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
19. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.

If operating a power tool in a damp location is
unavoidable, use
a
ground fault circuit
interrupter (GFCI) protected supply. Use of an
GFCI reduces the risk of electric shock.
Personal safety
10. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the influence of drugs, alcohol or
20. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
21. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23. Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the power
tool for operations different from those intended
could result in a hazardous situation.
medication.
A
moment of inattention while
operating power tools may result in serious
personal injury.
11. Use personal protective equipment. Always
wear eye protection. Protective equipment such

The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the bit will stop turning.
CAUTION:
•
•
As soon as the torque limiter actuates, switch off
the tool immediately. This will help prevent
premature wear of the tool.
Bits such as hole saw, which tend to pintch or
catch easily in the hole, are not appropriate for this
tool. This is because they will cause the torque
limiter to actuate too frequently.

chuck assembly is installed on the tool. The drill
chuck assembly may be damaged.
Also, the drill chuck will come off when reversing
the tool.
Pressing excessively on the tool will not speed up
the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.
